Problems building RTEMS for ARM on Ubuntu 64bit

[rtems at soulscythe.com]

Hi

I'm trying to get RTEMS 4.9 for ARM running on my Ubuntu 10.04 x86_64 system.

I've downloaded the prebuilt toolchain and installed all of the  
packages successfully.

rtems-4.9-arm-rtems4.9-binutils-2.19-3.el5.x86_64.rpm
rtems-4.9-arm-rtems4.9-gcc-4.3.2-24.el5.x86_64.rpm
rtems-4.9-arm-rtems4.9-gcc-c++-4.3.2-24.el5.x86_64.rpm
rtems-4.9-arm-rtems4.9-gdb-6.8-11.el5.x86_64.rpm
rtems-4.9-arm-rtems4.9-newlib-1.16.0-24.el5.x86_64.rpm
rtems-4.9-autoconf-2.62-4.el5.noarch.rpm
rtems-4.9-automake-1.10.3-1.el5.noarch.rpm
rtems-4.9-binutils-common-2.19-3.el5.x86_64.rpm
rtems-4.9-gcc-common-4.3.2-24.el5.x86_64.rpm
rtems-4.9-gdb-common-6.8-11.el5.x86_64.rpm
rtems-4.9-newlib-common-1.16.0-24.el5.x86_64.rpm
rtems-4.9-release-0.21-1.el5.noarch.rpm

#alien -d rtems-4.9*.rpm

I've followed these instructions  
http://devkitpro.org/viewtopic.php?f=2&t=59 with no joy. And I've also  
looked at http://www.rtems.com/pipermail/rtems-users/2010-
February/006616.html but is has no solution.

Any ideas what i need to do?
thanks
